Isaria sinclairii is an entomopathogenic fungus of buried cicada larva.
It is found in native forests during autumn. Its spores attack insects, including cicada larvae. The fungus feeds on the nymph’s insides until it completely fills its body cavity. After the larvae die beneath the soil surface the fungi then send a stalk (40mm high) up from the surface. The stalk is topped with white spore-bearing structures which release powdery white spores. These spores fall to the ground ready to infect other cicada nymphs.
This fungus has yielded new prescription drug for multiple sclerosis. This fungus produces myriocin, from which the synthetic drug Fingolimod (trade name Gilenya) which has immunosuppressive properties. This was the first oral disease-modifying drug for multiple sclerosis.
